In this study an agricultural software was developed and tested. The software can determine the field efficiency, capacity, size, and other values for different agricultural machinery and their operations. Besides, the software can create map files for mapping programs and prepare documentation for study results. In the developed system, GPS (Global Positioning System) receiver was placed on the top of an agricultural tractor for determination of the field size and working route. Working speed, geographic position, time, and other data were transferred to the software via GPS receiver's RS232 communication port. During the study, agricultural operation time factors (active and passive, turning and idle travel, materials handling, cleaning clogged equipment, adjustment, lubration, refueling, waiting for other machines) were transferred to the software with the numerical keypad which plugged laptop USB (Universal Serial Bus) port. Duration of each agricultural operational time was determined using the software internal timers. Travels of the agricultural machinery on the field were monitored from the map which was created in the software. After developing the system, the software was tested for granule fertilization operation using a fertilizer broadcaster. The test processes were conducted on three equal sized parcels. From the test results of these parcels, field efficiency values of 67.82%, 68.97% and 65.40%, were obtained.
